Khan Academy: Chemistry: Thermodynamics and Entropy
A video lecture discussing the definition of entropy as the change of states and as the heat added to the system divided by the temperature added. The video reconciles these two definitions by going through examples to explain how they...
Khan Academy
Khan Academy: Thermodynamics: Thermodynamics (Part 4)
An introduction to the concept of a mole and its role in the field of thermodynamics. Using a periodic table, one learns how to calculate the number of moles a quantity of an element has, based on its atomic mass. Goes on to explain how...

An introduction to Kelvin. Example of a problem involving the ideal gas law.
Khan Academy
Khan Academy: Thermodynamics: Thermodynamics (Part 1)
Discussion of how gases generate pressure in a container and why pressure times volume is proportional to the combined kinetic energy of the molecules in the volume. [9:49]
Khan Academy
Khan Academy: Thermodynamics: Thermodynamics (Part 5)
Demonstrates an example problem involving the formula PV=nRT. After calculating how many moles, he uses Avogadro's Number of molecules per mole, to calculate how many atoms that amount would represent. [8:00in]

This lesson will introduce the second law of thermodynamics and define the term entropy, providing examples of entropy.
Crash Course
Crash Course Chemistry #18: Enthalpy
A crash course episode introducing what the state function is, and how it varies from a path-dependent function; why enthalpy change is different from heat; and the fact that bonds are energy and to form and break them they release and...
Khan Academy
Khan Academy: Chemistry: First Law of Thermodynamics/internal Energy
A video lecture defining the first law of thermodynamics and internal energy. Understand that energy is only transferred from one form to another and not created or destroyed. Also learn how measure the amount of energy something has as...
Khan Academy
Khan Academy: Chemistry: Entropy Intuition
A video lecture to explain what entropy is and what it isn't. Two definition of entropy are introduced and explored to show how they can be reconciled. Also investigated is the second law of thermodynamics and its relationship to...
Khan Academy
Khan Academy: Thermodynamics: Thermo Can
This project demonstrates how to power a juice-can boat with a lighted candle. The candle heats the air, causing it to expand and push against the 'thermal sail' of the can, and move across the surface of the water. [3:53]
Crash Course
Crash Course History of Science #31: Marie Curie and Spooky Rays
It's time to talk about one of the most awesome scientists: Marie Curie. She figured out ways to get an education despite limitations of her homeland, was the first woman to win a Nobel Prize, and was the first person to win two Nobel...
Crash Course
Crash Course History of Science #26: Thermodynamics
It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and others that didn't and then some ideas that...
University of Houston
University of Houston: Engines of Our Ingenuity: Julius Robert Mayer
A discussion of Mayer's colaboration with Robert Joule and the ultimate development of the first law of thermodynamics. Interesting, anecdotal and well-written. Includes some biographical information. (Text is the actual radio transcript...
